Slowly depolarizing electrical current preferentially activates C-nociceptors. We explored the differential contribution of A-delta and C-nociceptors in NGF-sensitized skin using slowly depolarizing transcutaneous electrical current stimuli, CO2 laser heat, mechanical impact, and A-fibre compression block. In 14 healthy volunteers, pain rating was recorded on a numeric scale at days 1-14 after NGF treatment. Ratings during A-fibre conduction block were investigated at days 3 and 7 post-NGF. Pain ratings to electrical, CO2 heat and mechanical impact stimuli were enhanced (>30%, p<.0005, ANOVA) at NGF-injection sites. Axon reflex erythema evoked by electrical stimulation was also larger at NGF-injection sites (p<.02, ANOVA). Diminution of pain during continuous (1min) sinusoidal current stimulation at 4Hz was less pronounced after NGF (p<.05, ANOVA). Pain ratings to electrical sinusoidal and mechahanges under pathologic conditions. The relationship between psoriasis and cardiomyopathy is understudied in Indian patients. We evaluated psoriasis patients for cardiomyopathy and other echocardiographic abnormalities. About 98 (MF=6731) patients with mild to moderate psoriasis aged 18-75years (mean±SD=42.12±12.79years) having no pre-existing metabolic syndrome and cardiovascular disorders were studied. X-ray chest, electrocardiogram and echocardiography were performed and interpreted by cardiologist for size of the left and right ventricles, left ventricle ejection fraction, diastolic function, pulmonary artery pressure and valve abnormality/regurgitation and their severity as per current guidelines/recommendations. The cardiomyopathies were defined according to standard diagnostic guidelines. Echocardiographic abnormalities were noted in 13 (13.3%) patients aged 19-75years (mean±SD=43.30±15.71years). The left ventricular diastolic dysfunction (grad
